Can anyone unseat Jon Jones as the world's top pound-for-pound fighter?

Jon Jones (20-1 MMA, 14-1 UFC) wants nothing less than to be the greatest fighter to have ever set foot on the planet. Is there anyone who can stop his ascension to that throne?

Even before Jones’ UFC 172 win over Glover Teixeira, he was already considered the sport’s top current pound-for-pound fighter, according to the USA TODAY Sports/MMAjunkie MMA rankings. If Jones continues his dominance in the UFC’s light heavyweight division, he may very well reach his goal.

But if he slips, who would be in place to take his place at the top of the rankings that were long dominated by Anderson Silva and Georges St-Pierre? Is it UFC featherweight champion Jose Aldo? Or will St-Pierre return from a self-imposed layoff, not to mention ACL surgery, to reclaim his spot at the top of the ranks?
